HEEL-TRIMMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 341,065, dated May 4, 1886. Application filed October 12, 1885. Serial No. 179,669. (No model.)

To all whom it may concern:

Be it known that I, AARON F. SMITH, of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful Improvements in Heel- Trimming Machines, of which the following is a specification.

This invention relates to heel-trimming machines employing a rotary cutter-head, to which the heel is presented while held by the hands of the operator, a rand-guide or thinedged plate, which is inserted in the groove between the rand or heel-seat and the counter of the boot or shoe,andatop-lift guard,against which the top lift bears during the trimming operation, said guard preventing the cutter from cutting into the top lift.

The invention consists in the provision of means whereby the rand-guide may be adjusted either in a direction at right angles to the axis of the cutter or in a direction parallel with said axis, and may be secured in any position to which it may be adjusted, as I will now proceed to describe.

Of the accompanying drawings, forming a part of this specification, Figurel represents a top view of the cutter-head and the accompanying devices embodying my invention. Fig. 2 represents an end view of the same. Fig.

3 represents a section 011 line w a", Fig. 1.

The same letters of reference indicate the same parts in all the figures.

In the drawings, (t represents a molded cutter mounted on a power-rotated arbor, b, and formed to impart the desired shape to the heel. The only peculiarity in the construction of the cutter is,that it has no rand-knives. In other respects the cutter may be constructed substantially as shown in Letters Patent granted to G.\Vet1nore, April 25, 1885, No. 316,710, or in any other suitable manner.

0 represents the top-lift guard,which has a flange or rest for the toplift, curved to conform to the peripheral curvature of the cutter, and located as close thereto as possible, and a flange or rest for the tread-surface of the top lift, said flange being at an angle to the edge-rest. The top-lift guard is supported rigidly in any suitable manner, preferably by the rest d, which is attached to the frame of the machine, and projects forward below the of a ring or plate formed to project over one I end of the cutter, as shown, and having a thin edge adapted to enter the crease between the rand or heelseat and the counter of a boot or shoe. The rand-guide is attached to a shank, f, which is secured adjustably to an arm, g, affixed to the supporting-frame h. The connection of the shank f to the arm 9 is effected by means of a clamping-plate, i, and a screw, j, passing through said plate and through a slot in the shank f. The plate t is free to move up and down on pins k k,-affixed to the arm so that when the screw j is loosened the shank f is released and can be moved in any desired direction on the arm 9. When the screw j is tightened,it presses the plate i firmly against the shank f, and thus confines the latter and the rand-guideinanyposition to which they may have been moved. The arm gpasses into a socket, m, Fig. 3, in the frame of the machine, and is held by a clamping-plate, a, forming one side of said socket, and a clamp ing-screw, 0, which passes through said plate into the frame of the machine. When said screw is loosened, the arm g may be adjusted lengthwise, thus adjusting the rand-guide in a direction parallel with the axis of the cutter, and causing one guide to project more or less over the cutter, according to the width or height of the heel. It will be seen, therefore, that the rand-guide maybe set so as to stand at any desired distance from the molded surface of the cutter and at any desired distance from the top 1ift guide.

It will be borne in mind that the rand-guide is fixed when the machine is in operation,and does not have a yielding movement, like the rand-guide shown in my above-named application.

The top-lift guide is preferably made adj ust' able, as described in my former application.

I claim- 7 1. The combination, with the rotary cutter and the top-lift guide, of the rand-guide adjustable both at right angles with and parallel with the axis of the cutter, and clamping de vices, substantially as described, for positively In testimony whereof I have signed my name IO holding said rand-guide in any of the said to this specification,in the presence of two subpositions. scribing witnesses, this 7th day of October,
